Question

Apart from iron deficiency, chlorosis is also induced by

• A. Excess of lime
• B. Excess of manganese
• C. Boron deficiency
• D. None of the above

Answer 1

The correct option is A Excess of lime

Apart from iron deficiency, chlorosis is also induced by an excess of lime.

Chlorosis is a condition in which leaves produce insufficient chlorophyll. As chlorophyll is responsible for the green color of leaves, chlorotic leaves are pale, yellow, or yellow-white. Lime-induced chlorosis, or leaf yellowing, is caused by alkaline soil conditions. The high alkalinity of soils can make iron or manganese unavailable to plants, causing leaf chlorosis. Pale to bright yellow leaves, particularly on the new growth, are common symptoms.

So, the correct answer is 'Excess of lime'
